Taxonomy:Synallaxis cinereus Wied, 1831, “Capitao Filisberto road,” southern Bahia, Brazil. Scientific name was long considered a junior synonym of S. ruficapilla, but recently shown to represent a separate species; S. whitneyi is a synonym. Forms a superspecies with S. ruficapilla and S. infuscata; this superspecies is suggested by some authors as being most closely related to S. frontalis, S. azarae and S. courseni on basis of plumage and vocal similarities. Monotypic.
